Thx guys.

JT51, the sound you described ("No clicking anymore from center console area or rubbing sound from what appeared the right front") is exactly what i hear in my car. This is terrible, $1100 at only 50 kmiles+.

Actually let me verify this before i spend the money. This sound can be heard only at aroung 25-30 mph and when the car is coasting (foot of the gas) even during braking. As soon as i put my foot on the gas even just a little, it'll go away. Does it sound like it's the drive shaft bearing?

Thx

That doesn't sound like the driveshaft because you should be able to hear it more when you press the throttle. Unless the noise only comes from running the car at very low RPMs. The U-joints might have seized up on you. In that case, you would have to replace the entire driveshaft.

I didn't notice the rpms but coasting at 25-30 mph it has to be low. So with a bad U-joints, it still needs a whole new driveshaft? I thought i was getting good news

thx

Amati5,

That was my sound, low rpm rubbing sound from what seemed right front and clicking sound from center console only between 25-32mph on a deceleration, the instant I accelerated the sound went away. The entire drive shaft was replaced and I no longer have those sounds.

The U-joints are not replaceable on the SC400 or 300. If someone says they can, they will ruin the shaft. Go to www.car-parts.com and you can get one for about $200.00. It will come with the Center SUpport Bearing as well.

Thx for the info guys. I guess i'll put the rear wheels on the jack stand and see if can hear it from the drive shaft.

thx

Just make sure your traction control is off, and you haveto hold the brake down slightly so there is some resistance

Just to update you guys with what was found with my car.

The driveshaft support was bad. New part was installed for a total of $280, part=130, labor=2.8 hrs =140. Noise is gone, I am a happy guy. This is from an independent shop which i have used for years.

Thx everyone for your inputs.

AMATI5;

What is the drive shaft support ?

2Lexus430s

It is a bearing that holds the center of the driveshaft in place.. it has a HUGE rubber bushing that lines the inside and allows of movement of the driveshaft. It Costs about $130 from Lexus or Irontoad.

London Bill

I suspected it would be the central rubber mounted bearing on the propshaft but the different terminology can lead to misinterpretation, good to know it comes sererate, many makers only sell the centre bearing as part of the whole shaft.

I see the parts manual calls it a support:

Thx TealLexus for the reply.

Crap! I think mine is on its way out. I might get a carbon fiber one custom made. Any reason why I shouldn't do this?

Hermosa

Can you share the part number of this driveshaft support before I go out and do something crazy with my driveshaft?
